Need advice on new ZL1 engine

[68-69-70Nova SSL78]

I was going to put it in my 55 chevy (with straight axle) but since the engine was very late to come out I opted for a 327 a just drive the car on the street all the summer. I have to say it's been a gas ser. No pun intened. And a small block to run around town works fine. So the ZL1 engine would for the time be just an investment. But I like the idea of #1 or #427 that might be the only 28K investment. Thats probably out of the question but I'll call my chevy dealer to see if thats possible.
Thanks you all that have given advice. Ed
